ROLLER IBEARING- Application filed December 24, 1925, Serial lio. 77,58, and in Italy February I, 1825.

' The present invention refers to a bearing, the brasses of which consist in a link chain which in distended condition presents one or more rows of parallel rollers in running contact with each other supported by means of pins upon the sides of U like shaped links or brackets jointly connected with each other and which link chain is arranged in" the sta-- tionary bearing so that the webs of the brackets are leaning against and are firmly.

which the diameter may not be known with .exactness and is simply wound around the circumference of the shaft, the remaining poi'tion of the link chain is detached and the two ends connected by an apposite link look.

In the drawin Fig. 1 shows 51c improved roller bearin in a front view.in the right hand half 'an in a sectional .middle'view in the left hand half.

Fig. 2 .is a sectional view according to line 22 of Fig. 1. Fig. 3 isthe detail of a roller. Fig. 4 is a detail of a link chain withone 7 row of rollers.

in rotating these Fig. 5 is a detail of a link chain with two rows of rollers.

Fi 6 shows the chain lock in two views whic lock serves to connect the two ends of the link chain. I i

In these figures in which the same numbers indicate the same or similar parts 1 is the base of a shaft bearing, 2 the cover and 3 an annular oscillating body having outer spherical surface adapted within a corresponding surface of the base'land of the cover 2. Within the oscillating body 3 are arranged two annular ieces 4 the dis.- tance of which can be regu ated b threaded pins 5 threaded with threads '0 opposite pitch within the two annular pieces so that pieces can 'be regu ated. The annular pieces 4 are provided at its interior with a'spheri- 1 cal surface the center of which corresponds with the center of the bearing. Of the same conformation as the inner surface of the annular pieces 4'is the outer surface of the the rol ers wiiii ins the distance of these double row of ro lers and Fig. 5 illustrates a detail of this double row of rollers. In

'these figures the rollers 8 are rotatably supported upon the pins 7 which penetrate the thicknesses of the sides of the .U shaped brackets and split pins 9 attraversethe end intermediate webs of the brackets 6 forma portions of the pins 7 at the outside of the brackets and prevent the axial displacement of the rollers and the rotative displacement ofthepins.

- Fig. 4' hows a link chain with only one row of rollers. In this figure the brackets 6 are again of U shapewith a curvature of theintermediate webs to correspond with the inner curvature of the annular rings 4 and these brackets are jointly connected with each other on the axis of one row of rollers supported 11 on pins 7 traversing the sides of the brac ets 6 and locked at the outside of the brackets. by split pins 9.'- The ends of the chain are coupled together by a' special lock of which Fig. 6 shows a type adapted for a two roller row'link chain. This lock consists of two specialend brackets the end rollers o the chain and to constitute 'in connection with a threaded rod the link chain and to keep same in a tend condition.

. ets 10 adapted to support as the other brack- 12 are holes in the wallsIof "the rollers I which during the quick rotation ofthe rollers provocate an aspiration of lubricating oil upon the ins of the brackets.

The specia shape of the annular pieces 4 and the means 5 for varying its distance allowin to re ulate the exact contact of the shaft also allow to radually eliminate the clearance which may e created during the working of the bearingcreating thus a roller bearing which can be regulated.

During the rotation of the shaft'the rollers in contact with it are all put in rotation in the same direction. and without any friction as each roller does not encounter other resistance, than that upon its proper pin. The rollers. of this first row act upon airs of the corresponding rollers ofthe adthe load is thus divided upon a bigger number of pins or rollers than with the one row roller hearing.

1. A roller bearing for a rotating shaft comprising in combination, a plurality of links forming a connected chain, a roller rotatably secured in each of said links, a pair of rings forming a concave race, each of said links having a'convex' portion adapted' to rest in said race, means for connecting the ends of said chain, and means for moving said rings relatively to each other.

2. A roller bearing comprising a link chain, a plurality of rollers loosely mounted and arranged thereon in two annular rows, means to maintain the rollers of one row in rolling contact with the corresponding rollers of the adjacent row, said rollers being supported by pins carried by the side portions of U-shaped links connected with each other to ,form th link chain, and an outer stationary bearing in which the chain is are ranged so that the intermediate websof the links remain in contact with and are firmly to form a link chain, and an outer stationary bearing in which the chain is arranged so that the' intermediate webs of the links or brackets are firmly supported by the inner wall of the bearing, the rollers being contact with the shaft which'is to be supported by the bearing. 1

4. A roller bearing, comprising a link chain, a plurality of rollers loosely mounted and arranged thereon in two annular rows, means to maintain the rollers of one row in rolling contact with the corresponding rollers of the adjacent row, said rollers being supported by pins carried by the side portionsof U shaped links connected with each other to form the link chain, and a pair of rings adjustably arranged with respect to each hther and symmetrically arranged with respect to the middle plane of the bearing,

said rings having an inner spherical surface.

which corresponds with the outer surface of the intermediate webs so that the exact contact ,of the rollerswith the shaft can be regulated.

5. A roller bearing comprising a link chain, a plurality of rollers loosely mounted" and arranged thereon, said rollers being supportedby pins carried by the side portionsv of U-shaped links connected with each other to form a link chain, and a pair of rings'adjustably arranged with respect to each other,

and symmetrically arran ed with respect to themi-ddle plane of the caring, said rings having an inner spherical surface which corresponds with the outer surface of the intermediate webs of said links so that the exact contact of the rollers with the shaft can be regulated.
